Abstract：
Herein, a chemophenetic significance, based on the phenolic metabolite profiling of three Senecio (S. hercynicus, S. ovatus, and S. rupestris) and two Jacobaea species (J. pancicii and J. maritima), coupled to morphometric data, is presented. A set of twelve morphometric characters were recorded from each plant species and used as predictor variables in a linear discriminant analysis (LDA) model. From a total 75 observations (15 from each of the five species), the model correctly assumed their species\' membership, except for 2 observations. Among the studied species, S. hercynicus and S. ovatus presented the greatest morphological similarity. A phytochemical profiling of phenolic specialized metabolites by UHPLC-Orbitrap-MS revealed 46 hydroxybenzoic, hydroxycinnamic, and acylquinic acids and their derivatives, 1 coumarin and 21 flavonoids. Hierarchical and PCA clustering applied to the phytochemical data corroborated the similarity of S. hercynicus and S. ovatus, observed in the morphometric analysis. This study contributes to the phylogenetic relationships between the tribe Senecioneae taxa and highlights the chemophenetic similarity/dissimilarity of the studied species belonging to Senecio and Jacobaea genera.
摘要：
在这里，化学表型的意义，基于三种Senecio(S.hercynicus,S、Ovatus，和S.rupestris）和两个Jacobaea物种（J.Pancicii和J.maritima)，结合形态测量数据，是presented。从每个植物物种中记录了一组十二个形态特征，并在线性判别分析（LDA）模型中用作预测变量。从总共75个观察结果中（5个物种中的每个15个），该模型正确地假定了它们的物种\'成员，除了2个观察。在研究的物种中，虫草属和卵黄属在形态上表现出最大的相似性。通过UHPLC-Orbitrap-MS对酚类专门代谢物进行的植物化学分析显示，有46羟基苯甲酸，羟基肉桂酸，和酰基奎尼酸及其衍生物，1香豆素和黄酮类化合物21。应用于植物化学数据的层次聚类和PCA聚类证实了草鱼和卵黄的相似性，在形态计量学分析中观察到。这项研究为Senecioneae类群之间的系统发育关系做出了贡献，并强调了属于Senecio和Jacobaea属的所研究物种的化学表型相似性/差异性。
